Autostop HD
Combined Red-Light and Speed Enforcement Camera
Autostop HD is the result of Sodi Scientifica’s experience acquired since 1964 in traffic instrumentation. It is a high-performance, multipurpose device, capable of enforcing violations in an indisputable manner in order to simplify operators’ life and improving road safety.

o Motion video clip
o Infrared or white light  flash module
o High operational efficiency
o Automatic number plate recognition
o Connection via tablet PC
o Automatic signalling of malfunctions or vandalism

When installed at a traffic light junction, Autostop HD automatically detects violations of:
• Red light
• Speed (on red or green light)
• Failure to comply to traffic light signals
It may also be installed on any road or highway as an automatic speed enforcement camera
The North American version of Autostop HD is provided with the UL 61010 marking.

Autostop HD is a modular device consisting in the following elements.

At a traffic light junction, Autostop HD captures two High Definition digital images (up to 18 megapixels) for each violation. The first when crossing the stop line (in the USA version: before crossing it) the second when the vehicle is in the middle of the intersection. Sodi Scientifica’s high resolution camera system enables the positive identification of an offending vehicle from a single photograph through a clear view of the following elements:
• state of traffic signals (green, amber or red)
• offending vehicle model and make
• vehicle’s number plate automatically read by the in-built OCR
When installed away from a signalized intersection, the system captures just one picture of the speeding vehicle.
Images are always clear, authentic and indisputable, and are automatically protected through digital signature with public key encryption.
IR or visible light flash module
The camera can be equipped with an invisible infrared or white light flash unit, automatically activated when lighting is insufficient. With IR flash device, pictures are black and white by day and by night.
Optional digital video camera
A digital video camera operating with natural light is optionally available, to record a 10 seconds video (4 seconds before and 6 seconds after the vehicle crossed the stop line).

Automatic local or remote download of data
All enforcement data may be automatically downloaded through wired (fiber optic, UTP cable, etc.) or  wireless (UMTS or HSUPA) networks.  Without any interruption, operators can also set the site parameters from the office or locally trough a special encrypted mass memory “Data Key” or by portable or Tablet PC. In case of data loss or damage, the device allows it to be recovered in a 30 day span.
High operational efficiency
Thanks to its innovative Photo-Burst technology, Autostop HD provides unparalleled simultaneous enforcement rate across a full three lanes of traffic and three different red light times
Non-intrusive connection to the traffic light
In order to keep Autostop HD from interfering with the traffic light system, its state (green, amber or red)  is gathered through a fiber optic system. 
Automatic signalling of malfunctions or vandalism
Thanks to the sophisticated sensors mounted on the pole and in the road side cabinet, the optional alarm system activates a siren and signals any acts of vandalism or malfunctions, to both the officers (via SMS) and the instation.
Autostop HD also signals the operators when the measured amber phase is lower than the programmed time threshold.
Low visual impact
Autostop HD is particularly compact and can be installed on both sides of the road. The entire photo/video and flash module is mounted on a single pole and the road side cabinet can be placed within 60 metres from it.
Backvelox HD software
The system is supplied with a free tool called Backvelox HD. This is very useful when some functions are not integrated by the Back Office Enforcement Processing Software in use, such as importing and viewing data, validating and printing them and exporting them .
In order to safeguard citizen’s privacy, Backvelox HD automatically makes all non-offending number plates illegible.
